R1 Concepts 623-03038R RNC Series Drilled Brake Rotor

The R1 Concepts 623-03038R RNC Series Drilled Brake Rotor delivers reliable stopping performance with a precision-engineered cross-drilled design. Built to OEM specifications and beyond, this rotor is manufactured from G3000 grade cast iron for consistent strength, thermal stability, and long service life.

The cross-drilled hole pattern improves heat dissipation and ventilation across the rotor face, reducing brake fade during repeated or aggressive braking. The rotor's protective zinc nano-coat (RNC) finish guards against corrosion on non-friction surfaces, maintaining a clean appearance and extending the life of the rotor beyond that of uncoated alternatives.

Key Features:

• Cross-drilled design for enhanced heat dissipation and reduced brake fade
• G3000 grade cast iron construction for durability and consistent performance
• Zinc nano-coat (RNC) corrosion-resistant finish on hub and vane surfaces
• Precision-machined braking surface for smooth, quiet operation
• Double disc ground brake surface for faster, more even pad bed-in
• Manufactured to OEM fitment specifications — no modifications required
• Compatible with OEM-style replacement brake pads

The R1 Concepts RNC Series rotor is an excellent upgrade or direct replacement for worn or warped factory rotors, providing improved thermal management and corrosion resistance in a single drop-in part.
